THREAD IRIEY.[AI1\TIEIR FOR SPOOLING GUIDES.

Application filed February 29, 1924. Serial No. 696,096.

To all whom it may concern:

Be it known that 1, CHARLES F. ROYCE, a citizen of the United States,residing at lVatertown, in the county of Litchfield and State ofConnecticut, have invented certain new and useful Improvements in aThread Retainer for Spooling Guides, of which the following is aspecification.

This invention relates. to thread retainers i for spooling guides andparticularly to a substantial contact with one another in order toprevent the threads from jumping outwardly between the fingers, it beingnecessary in applying thethread to the guide to snap it in place betweenthe fingers, so that a retention of the thread in the guide is assuredat all tim s.

Another object of the invention is to provide a guide which may be madein one piece and stamped from sheet material adapted to be readilyapplied to the end of the thread guide provided with the guiding groove,so that the thread may be placed in, or removed from said groove, in aneasy and eflicient manner.

The invention also comprehends other objects and improvements in thedetails of construction and arrangement of the retaining member on theguide for carrying out the above objects which are more articularlydescribed in the, following detailed description and claims, directed toa preferred form of the invention, it being understood however thatvariations in the specific formation of the retaining member and itsassociation with the guide member may be made within the scope of thedescriptionand claims.

In the drawing, forming a part of this application Figure 1 is an endelevation of a thread guide provided with the retaining member formingthe subject of this invention, said guide being shown as mounted on thethread board.

Figure 2 is a side elevation of a guide, showing the manner of applyingthe retaining member thereto.

Figure 3 is a disassembled perspective view of th guide member and theretaining member.

1 indicates the thread board of a spooling machine which is of anydesired character usual to the construction of spooling machine andprovided with securing means 2 adaptedfor securing the usual threadguide indicated at 3 to said thread board.

The outer end of the thread guide projecting beyond the end of thethread board 1, is rounded as indicated at 4c, and'provided with a guidegroove 5, for receiving and guiding the thread in a well-known manner.In the use of guides of this type, which are well. known in the art. ithas been found that as the machine is started or stopped, the threadswill jump out of the respective guide grooves and that it will requirecon siderable time in starting up the machine and also in replacing andstarting all of the threads in their proper guide grooves in thecontinuation of the operation of the machine. These guide members 3 areused principally in connection with spooling machine for spooling threadsilk on yard and one hundred yard spools.

This invention provides a thread retain ing member, which is indicatedgenerally at 6 and is formed of a single piece of sheet ma terialadapted to be formed into a pair of spaced parallel retaining plates 7which are connected by a web 8 adapted to seat in a recess 9 formed inone edge of the thread guide adjacent the outer end thereof, so that theouter face of the web 8 and the edge of the thread guide 3 lie insubstantially the same plane in order to prevent the threads fromcatching thereon, which would sliver said threads and give an imperfectspool in the completed winding. The outer free ends of the retainingplates beyond the end of the web 8 are formed with aligned openings 10,adapted when positioned on the thread guides 3 to align with an opening11 in the outer end of said guide for receiving a retaining groove 12,which rigidly mounts the retaining member on the outer end of the guide.Beyond the openings 10 and beyond the end of the guide, one of theretaining plates is bent toward the other plate as indicated at 13,while the end portions of both plates beyond this bent portion 13 arecurved in relative opposite and outward di-, rections as indicated at14c to provide thread receiving clips. The curved portions are normallyin substantial contact with one another as indicated at 15 forpreventing the threads from jumping outwardly between the ends of theplates 7, so that it is effectively retained in the guide groove by'theretainingmember, the curved or offset portion 13 being vpro ided in theone plate, so as to position the contact of the plate-to one side of thegroove to prevent the thread from catching between'the plates which,under some'conditions might effect a breaking of the thread, which is avery undesirable feature. a

With this retaining member for the thread guide, it will be clear that athread may be positioned in the guide and retained therein by feeding itthrough the receiving lip and drawing it down between thecontactingportion of the retaining plate into the guide groove '5, sothat in the operation of the machine, said'plates will effectivelvretain the threadsin the groove, as the inner faces of these plates arein intimate contact with the outside edges or sides ofthe thread guidev3, as may be clearly ascertained from an inspection of Figure 1.

Inthis way, it will be seen that the thread is effectively guided andretained in the guide, and that theconstruction of the member is suchas'to prevent the 'slivering on breaking of the threads in case it comesin contact with the retaining member.

It is therefore believed to be clear from the above description, that aneflicient and simple retaining member for retaining thread in a spoolingguide has been provided, which may be constructed of a single piece ofsheet material and efliciently and rigidly connected in cooperation withthe outer end of the thread guide.

WVhat is claimed is: V

1. A thread retainer for guides of spooling machines including a memberhaving a pair of retaining plates mounted on the sides of the threadguides and projecting beyond the end of said guide which is formed witha guide groove, said plates being formed to contact beyond the end ofthe guide and hav; ing outwardly directed lips at the free ends thereoffor effectively receiving and retain ingda thread in the guide groove ofsaid gui e;

2. A'retaining member for thread guides of spooling machines comprisinga single piece of sheet material forming a pair of spaced parallelretaining plates joined by a web portion connecting the-sides thereof atone end portion thereof, the opposite end portion being formedinto'thread receiving lips atthe outer end and adapted for contact withone another for retaining 'athread in the guide groove of aspooling'guide when positioned thereon tocooperate "with said guide.

In testimony whereof]: aiiix mysignature,
